Generate Random Colors with Style Presets Generate random colors with optional style constraints like pastel, vibrant, or warm.

The generator uses HSL color space for randomization because it provides intuitive control over color properties. Each preset constrains different HSL ranges: pastel uses high lightness (75–90%) with moderate saturation (40–70%); vibrant uses high saturation (80–100%) with mid lightness (45–65%); dark uses low lightness (10–30%); warm constrains hue to 0–60° (red through yellow); cool constrains hue to 180–300° (cyan through purple); earthy uses low saturation (30–60%) with low-mid lightness. The hue for unconstrained presets is uniformly distributed across 0–360°. The generated HSL values are converted to HEX for display and copying. This approach produces more visually harmonious random colors than pure RGB randomization, which tends to produce muddy, unpleasant colors because it doesn't account for human color perception. The Math.random() function provides pseudo-random values; each generation is independent and unrepeatable.
